Hi Robert,
I’ve only had luck with PLA so far, as I do not yet have an enclosure. I tried some flexible filaments like TPU and the OOKMA brand flexible media… but it didn’t work out. This was due to two reasons 1: it is almost impossible to thread. The filament goes off laterally into the module innards instead of through the nozzle. 2: If all the planets come into alignment, and the Sun is at its zenith, and the wind is blowing south-easterly at precisely two knots and you actually get the media threaded, then the issue is that the snapmaker seemed unable to pull the media through the nozzle for a print. There may also be a third issue with feeding the filament. The way the filament holder is situated on the back of the SM causes the feed to rely upon the rigidity of the media: it swoops up for a bit, before turning down into the nozzle. Flexible media is too limp to do this.
Issue 1: can be addressed by using @jjestings device he designed for this purpose. I do not know the ramifications of using this device as it relates to your SM warranty, so I’m not recommending here… just informing.
Issue 2: May possibly be alleviated by using settings that are much more conservative than PLA settings. @jjestings also shares his wisdom regarding this as well. He states using these settings along with his device, he can print flexible media.
Issue 3: Might be alleviated by using an alternate mount, or a reverse mount of the media. Not sure… I didn’t get far enough without being able to implement the above two solutions.
@jjestings thread is here: Flexible Filament adapter is needed if you care to look.
BUT – I really want to know if you were successful printing ABS objects on your Snapmaker. When you said you pretty much print ABS – was it on the SM or another device? If it was on the SM, could you share your secret to successful printing?
Thanks
